Fig. 2 and Fig. 3 are respectively the three-dimensional schematic diagram and the mechanism motion diagram of the sitting-up mechanism, the sitting-up mechanism mainly realizes the patient's getting up by the rotation of the bed boards 2, 4, 5, and the sitting-up mechanism mainly consists of a rotating arm 12 and a nut seat. Support arm 13, screw mandrel 14, universal joint 15, axle 16, belt 17, motor 18 form. Rotary arm 12 one end is equipped with roller, joins with bed board 2,4,5, and the other end is hinged with support arm 13 with nut seat, and the center is hinged with bed frame 1. The support arm 13 with the nut seat is connected to the screw rod 14 by threads, the other end of the screw rod 14 is connected to the shaft 16 through the universal joint 15, the universal joint 15 is connected to the bed frame 1, and the shaft 16 is connected to the motor 18 through the belt 17 transmission. When the bed board is flat, the person lying on the bed is the same as an ordinary hospital bed. When it is necessary to sit up, the motor 18 in the figure drives the shaft 16 to rotate, and the shaft 16 drives the screw mandrel 14 to rotate through the universal joint 15. The support arm 13 of band nut seat pushes to the right, and the pivoting arm 12 that is hinged with the support arm 13 of band nut seat just rotates around the middle fulcrum, and the rollers drive bed boards 2, 4, 5 to rotate around the fulcrum, thereby making people sit up. the

Fig. 4 and Fig. 5 are respectively the three-dimensional schematic diagram of the curved leg mechanism and the schematic diagram of the mechanism movement. The curved leg mechanism of the multifunctional nursing bed includes a rotating arm 19, a nut seat 20, a screw rod 21, a universal joint 22, a shaft 23, and a belt 24 , Motor 25. One end of the rotating arm 19 is in rolling contact with the roller and the bed board 9, the other end is hinged with the nut seat 20, the middle fulcrum is hinged with the bed frame 1, the nut seat 20 and the screw rod 21 are connected by threads, and the screw rod 21 and the shaft 23 pass through a universal joint 22 is connected, shaft 23 and motor 25 are driven by belt 24. When the bed board is flat, the feet are placed flat on the bed when the person is lying down, and when the legs need to be bent upward, the motor 25 drives the shaft 23 to rotate, and the shaft 23 drives the screw mandrel 21 to rotate through the universal joint 22, and the screw mandrel 21 drives the nut seat 20 Translating, the rotating arm 19 hinged with the nut seat rotates around the middle fulcrum, and the rollers at the end of the rotating arm 19 drive the bed boards 9 and 10 to rise. Because it is a parallelogram mechanism, the bed board 10 remains horizontal all the time. When the legs need to be bent downward, Motor 25 can be commutated. the

Fig. 6 and Fig. 7 are respectively the three-dimensional schematic diagram of the rollover mechanism and the schematic diagram of the movement of the mechanism. The rollover mechanism includes a pivoting arm 26, a pivoting arm 27, a nut seat 28, a screw mandrel 29, a shaft 30, a belt 31, a belt 34, and a motor 32 , hand rocker 33. Axle 30 is parallel with screw mandrel 29, and effect is in order to make nut seat 28 can only move in horizontal direction and can not rotate around screw mandrel 29, two fixing arms with rollers are arranged on nut seat 28, and rotating arm 26 and One end of the rotating arm 27 is in rolling contact with the bed board 4 or the bed board 2, and the other end is stuck in the rolling contact of the support arm of the nut seat 28. It is connected with the motor 32 through the belt 31. When the bed board is flat, the person lying on the bed is the same as an ordinary hospital bed. When the right (left) rollover is required, the motor 32 in the figure drives the screw mandrel 29 to rotate, and the screw mandrel 29 drives the nut seat 28 to the left ( Right) moves, and the support arm of nut seat 28 moves relatively with pivoting arm 27 (26), makes pivoting arm 27 (26) rotate counterclockwise around the middle fulcrum so that bed boards 4,5 (bed boards 2,5) turn right (left) ) turn over, when the manual drive operation can be replaced with the hand rocker 33 to rotate and drive the belt 34 to achieve. the

Fig. 8 and Fig. 9 are respectively the three-dimensional schematic diagram of the defecation mechanism and the schematic diagram of the mechanism movement. As shown in the figure, the defecation mechanism is mainly connected with the hand rocker 36 through the universal joint 37 through the screw mandrel 38, and the screw mandrel 38 is connected with the nut by thread. Seat 40 links to each other, and nut seat 40 is hinged with bed board 7, and the connecting rod 42 welded with bed board 7 is hinged with connecting rod 41, and the other end of connecting rod 41 is hinged on the base plate 11, and base plate 11 has roller 39. When needing to defecate, shake the hand rocker 36 to drive the screw rod 38 to rotate, the nut seat 40 moves under the action of the screw transmission, the bed board 7 just rotates around the fulcrum of the bed board 35, and the bed board 7 drives the connecting rod through the connecting rod 42 while rotating 41 rotates, and connecting rod 41 moves the bedpan on the base plate 11 directly below the bed board 35, and waits for defecation to take back and handle. the

Fig. 10 is a schematic diagram of the mechanism movement of the hand rocker and the shaft detachment mechanism of the multifunctional hospital bed. The sitting up, rollover, and leg bending mechanisms all have a hand rocker. The hand rocker structure includes a rocker arm 43 and a hand sleeve 44. , axle 48, have a rectangular hole 47 on the hand sleeve 44, axle 48 welding spring 45, spring 45 connects leaf spring 46, the width of rectangular hole 47 is consistent with leaf spring 46 broadband. The shaft 48 is connected with the motor and the screw mandrel, and the shaft 48 is smoothly connected with the inner wall of the hand sleeve 44. The shaft 48 will not drive the hand sleeve 44 to rotate when it rotates. When the spring leaf 46 moves to the position so that it is just stuck in the rectangular hole 47, the hand sleeve 44 can drive the shaft 48 to rotate. When it is necessary to separate the hand rocker from the shaft, just press the spring leaf 46 to make it disengage Rectangular hole 47, thereby just realized the separation and combination of manual drive and electric mechanism. the

Fig. 11 is a three-dimensional schematic diagram of the interlocking mechanism for sitting up and rollover of the multifunctional hospital bed. The nut seat 28 is welded with the limit frame 50, the shaft 49 is welded with the connecting rod 54, the connecting rod 54 and the connecting rod 55 are hinged, and the baffle plate 51 has a The chute 53, the end of the connecting rod 55 is stuck in the chute 53, the baffle plate 51 can rotate around the center hole 52, for the sake of safety, the sitting-up mechanism and the rollover mechanism must be interlocked, that is, they cannot be rolled over after sitting up , After rolling over, you can no longer sit up, and only when the bed is flat can you perform other exercises. Nut seat 28 is welded limit frame 50, and when nut seat 28 moves left or right, the left end of limit frame 50 or the right end just can move to the top of rotating arm 12, and now rotating arm 12 is subjected to limit frame 50 left-hand or right-hand restriction, pivoting arm 12 just can not rotate upwards again, and thus rollover mechanism has just played restriction to sitting up mechanism. Simultaneously, when the sitting mechanism moves, the shaft 49 rotates counterclockwise, the shaft 49 drives the connecting rod 54, the connecting rod 54 drives the connecting rod 55 to rotate, and the connecting rod 55 moves in the chute 53 of the baffle plate 51, thereby driving the baffle plate 51 rotates counterclockwise around the central hole 52. When rotating 90°, the two ends of the baffle plate 51 limit the movement of the pivoting arm 26 and the pivoting arm 27, thereby realizing the restriction of the sitting up mechanism to the rollover mechanism. the

The utility model has been described above in conjunction with the best embodiments, but the utility model is not limited to the above-disclosed embodiments, but should cover various modifications and equivalent combinations based on the essence of the utility model. the
